Correct Installation Of The ESBE 3 Port Valve
Supplied By Daikin For Domestic Hot Water

Altherma 3 Port Valves
•This has caused a great deal of confusion for installers in the past. This valve
always used to be site supplied.
•We recommended a valve in our training course. A Honeywell V044C. This is a
spring return valve, not a mid position valve. Mid position valves are not permitted as
the system is not capable of parallel operation of space heating and DHW
production.
•Despite this some installers have used the mid position valve. If this is the case then
some wiring can be altered from the valve to force the correct valve operation. For

some wiring can be altered from the valve to force the correct valve operation. For
some Honeywell mid position valves the white and grey can be linked to enable this
operation. If the installer has fitted the wrong valve it is up to them to make enquires
with the manufacturer of the valve about re-wiring.
•From July 2008 Daikin have started supplying there own valve (to eliminate this
confusion on site). This valve is manufactured by ESBE & is essentially a mixing
valve. It is VERY IMPORTANT that the installer obeys the installation instructions in
the installation manual. Failure to do this will result in a mixing of water between the
space heating and DHW circuit.
•Note – This valve is supplied with the NEW B Series DHW Tanks
•Please refer to the manual attached in the next slides for installation instructions

Once you have the valve body installed, turn the red plate on the valve body so that the
indicators 0 – 10 are between the sanitary hot water and the space heating loads.
Install the white plastic blocking pointer to the shaft and turn to mid position which is
number 5 as shown in the picture.
Then fit the motor holding pin at position 5 if installed this way.
After this fit the motor to the valve body and secure with the centre pin.

Finally set the jumper pins as shown on the
previous page, when the motor is powered
up for the first time you need to ensure that
you change the jumper pins so that the white
blocking pointer motors towards the sanitary
hot water.
Once the wiring is correct turn the power on.
